Well...I had a 72 gallon tank I wanted drilled...and no glass shop would do it. They said it would shatter, especially if it was tempered glass. 
-no fish shop would drill it either. 
 
-where did you get them drilled, and do they drill older tanks, or just new ones? ( I have a 10 yr old 72 gallon tank.) 
Since I'm in Ontario, I'm hoping to get a national company mentioned. 
 
Has anyone ever had a tank crack while it got drilled? 
 
Thanks 
 
Michael
